## What it is
DaggerMock is a JUnit rule that makes it easy to override Dagger 2 provided objects with Mockito mocks in Java or Kotlin tests. It scans @Mock-annotated test fields and substitutes them into the Dagger component, avoiding the need for custom TestModules and TestComponents.

## Use cases
- override dagger 2 dependencies in junit tests
- mock objects injected by dagger in android tests
- unit test android services using mockito and dagger
- replace dagger module providers with mocks without test modules
- write espresso tests with mocked dependencies

## When to choose
- you use Dagger 2 with JUnit and want simple mock overrides
- you want to avoid boilerplate TestModule/TestComponent setup in tests
- you write Android tests in Java or Kotlin with Mockito

## When to avoid
- you use Hilt or Koin instead of Dagger 2
- you need a maintained solution - the project is in maintenance mode
- you need to mock static or null fields, which are unsupported

## Facets
- artifact type: library
- maturity: maintenance
- function: testing, mocking
- domain: testing, android-tools, developer-tools
- platform: jvm
- tags: dagger2, junit-rule, mockito, espresso, dependency-injection-testing, android
